1. A power supply system comprising:
a first electrical storage device;
a second electrical storage device;
a load circuit including a rotary electrical machine;
a power circuit that connects the first and second electrical storage devices to the load circuit;
a power controller that controls a first output power of the first electrical storage device and a second output power of the second electrical storage device in a normal mode or an output priority mode that allows an output, which is larger than that in the normal mode, from the power circuit to the load circuit;
a first cooler that cools the first electrical storage device;
a second cooler that cools the second electrical storage device; and
a cooling output controller that controls a first cooling output of the first cooler and a second cooling output of the second cooler,
the power supply system further comprising a cooling remaining-capacity acquirer that acquires a first cooling remaining-capacity increasing or decreasing depending on a difference between a first maximum cooling output and the first cooling output of the first cooler and a second cooling remaining-capacity increasing or decreasing depending on a difference between a second maximum cooling output and the second cooling output of the second cooler,
the cooling output controller being configured such that:
in a case where an operation mode of the power controller is the output priority mode and the first cooling remaining-capacity is equal to or more than a first cooling remaining-capacity threshold value, the cooling output controller increases the first cooling output as compared with a case where the operation mode is the normal mode, and
in a case where the operation mode is the output priority mode and the second cooling remaining-capacity is equal to or more than a second cooling remaining-capacity threshold value, the cooling output controller increases the second cooling output as compared with a case where the operation mode is the normal mode.
